Flying drones inside burning buildings while looking for disaster survivors is incredibly hard, but it’s also one of the most promising applications of the machines. This drone is one of the first prototypes that might just be ready for disaster sites. ,

It looks like the sun… but it isn’t. It’s a brand new type of artificial skylight called CoeLux which, for the first time, recreates the scientific process that makes the sky appear blue. It also creates an illusion of depth to make the ‘sun’ appear to be far above. Lux takes an exclusive look. ,

DARPA’s Airborne Launch Assist Space Access program (ALASA) seeks to propel 100-pound satellites into low Earth orbit (LEO) within 24 hours of call-up, all for less than $1 million per launch. The current ALASA design envisions launching a low-cost, expendable launch vehicle from conventional aircraft. Serving as a reusable first stage, the plane would fly to high altitude and release the launch vehicle, which would carry the payload to the desired location. The program is moving ahead with rigorous testing of new technologies that one day could enable revolutionary satellite launch systems that provide more affordable, routine and reliable access to space. ,

A tugboat (tug) is a boat that maneuvers vessels by pushing or towing them. Tugs move vessels that either should not move themselves, such as ships in a crowded harbor or a narrow canal, or those that cannot move by themselves, such as barges, disabled ships, log rafts, or oil platforms. Tugboats are powerful for their size and strongly built, and some are ocean-going. Some tugboats serve as icebreakers or salvage boats. Early tugboats had steam engines, but today most have diesel engines. Many tugboats have firefighting monitors, allowing them to assist in firefighting, especially in harbors. ,
